Specification of Letters Patent.

Application madman 29,1906. Boris-1N0. 808,669.

To all whom it may cancel-w.-

citizen of the United States, residing at New York, in the county of New York and Stateof New York, have invented certain new and useful Improvements in Saws, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to saws; and the object thereof is to provide an improved device of this class which is particularly desi ned for use in felling large trees, as shown an described in an application for Letters Patent of the United States filed by me February 2, 1906, Serial No. 299,095, and which may also be used for cutting logs from trees of this class when felled and for various other and similar purposes; and with this and other objects in view the invention consists in a saw constructed as hereinafter described and claimed.

The invention is fully .disclosed in .the following specification, of which the accompanying drawings form a part, in which the separate arts of my improvement are designated iiy suitable reference characters in each of the views, and in which Figure 1 is a transverse sectional View of a saw made according to my invention; Fig. 2, a view similar to Fi 1, but showing a modification; Fig. 3, a si e view of a part of a saw made as shown in Fig. 1; Fig. 4, a view similar to Fig. 1, but showing another modification Fig. 5, a side view of that part of the saw shown in Fig. 4 and Fig. 6 another view similar to Fig. 1, but showing another modification.

The saw which constitutes the subjectmatter of this application is designed in use to be given both a longitudinal and a rotary movement and is also designed principally for use in the felling of large trees, and the body portion a of the saw is preferably tubular in form, said body portion being provided with a longitudinal bore or passage a and said body portion of the saw is also provided with radially-arranged ports or passages a, which communicate with the longitudinal bore a and the object of the central longitudinal bore a and the radially-arranged ports or passages a, is to provide means whereby water may be forced into and through the saw when the latter is in operation, so as to keep the saw cool and to facilitate the cleaning thereof and also to clean the out formed by the saw in the tree which is being felled or the cut formed by the saw when dividing the gody of the tree into logs, which may also be one. Y

The teeth of the saw are formed on collars 1), adapted to .be secured to the bod portion of the saw and to be detached t erefrom when desired, and it will be understood that the number of the collars I) depend on the length of the saw and the transverse width of said collars, together with the she e of the teeth, and in practice the collars are secured to the body portion a of the saw, as indicated in Fig. 5, or so that the teeth on one collar will be at right angles to those on the ad'acent collar or collars.

n the construction shown in Fig. 2 the body portion a of the saw is an lar 1n crosssection, and the collar b is similarly formed, and it will be understood that the only diiference between the construction shown in Fig. 1 and that shown in Fig. 2 is in the fact that the body portion a of the saw is angular in cross-section.

The teeth 1) (shown in Fi s. 1 to 5, inclusive) project radially from t e collars b and -may be of any desired shape or form but in Figs. 4 and 5 I have shown a construction in which the body portion a of the saw is tubular in form and the-collars b are provided with curved teeth 12 having transversely-arranged cutting edges b*, which project in opposite directions, as clearly shown in Fig. 4, and the construction shown in Fig. 6 is similar to that shown in Figs. 4: and 5, with the exception that the collar b is rovided with three teeth b My invention 1s not limited, however, to any particular form for the teeth with which the collars b are rovided, and said teeth may be shaped or ormed in any preferred manner or as experience may decide to be best.

The object of forming the teeth separately from the body portion of the saw is to proa register with corre- It will be understood that the ends of the saw may be made in any desired manner, and,

as herembefore stated, my im roved saw is designed for special use, as own and described in the a plication for Patent of the United tates, hereinbefere referred to, in which suitable means are described for operating my improved saw, and in addition to the useherein s ified it will be apgiarent that my improv saw may be used or varieus othegslursoses.

Having y ascribed my invention, what I claim as new, and desim'to secure by Lettors Patent, is-

1. A saw-com If tubular body pertien andcollals taohably -conneeted there-' with and provided witkradially-arranged teeth, said am al'l'ltfigedifi i 'tudireal and transverse rows, substantia 1y as showliand described. B06

2. saw com rising a tu ar y portion and collars Xetachably connected therewith and provided with radially-arranged in longituditeeth, said teeth being arranged dtransverse rows, and thebodj ortion of thesaw being provided with radia orts or es, substantially as shownan descri ed. v

tel'fimen that I claim the' feregoing as my invention have signed my name, in'presenee oi the subscribing wit, this 28th day dumb, 1906.
